This invention relates to closure operators and more particularly to motor vehicle window operators.

The primary object of the invention is to provide means whereby the windows of a motor vehicle may be raised or lowered by electric energy, it being necessary for the operator to merely move an electric switch, completing a circuit.

Another object of the invention is to provide a device of this character which may be readily and easily installed in a motor vehicle door structure, novelvmeans being provided for adjusting the operating device to fit motor vehicle doors of various heights, insuring a true operation of the window operated by the device.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the' details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed (without departing from the spirit of theinvenion.

Referring to the drawings,

Figure 7 is a sectional view taken on line |1 of Figure 3.

Figure 8 is a diagram illustrating the circuit and switch, forminga part of the invention.

Referring to the drawings in detail, the reference character 5 designates a motorsyehicle door provided with the usual window guides 6 in which the window I moves.

The reference character i designates a channel bar to which the lower bar 9 of the window support is secured.

Channel bar II which forms a part of the door structure, also provides a support for the electric motor ll mounted in such a way that the motor view taken on line 0-4- shaft "thereof is disposed vertically, the upper end of the shalt l2, being formed with an enlargement l3.

Positioned directly above the upper end of the shaft I2, is the operating shaft indicated at H,

The bearing i1 is formed with a notch disposed in its upper end, for the reception of a 20 screw-driver. or similar positioning tool. Disposed directly above the bearing i1, is a lock washer I! which is provided with extensions 20 that fit within the threads of the cylinder I, holding the hearing I! in its adjusted position.

Lock nuts 2" and II also flt within the upper end of the cylinder It, to lock the. iatssembly. against rotary movement, when the shaft H is in operation.

At the lower end of the shaft I4, is an enlarge- 30 ment in the form of a disc 22, the enlargement fl being connected with the enlargement H, by means of the pin 28 fitted in openin s in the ends of mama n and u. A friction clutch member 24 isdisposed between the enlargements I3 and 35 12 and acts to transmit movement of the shaft it, to the shaft ll.

Pivotally connected with the collar ii, are arms 2!, which arms have pivotal connection with the bars 28 at points intermediate theends there- 40 of, the upper ends ofthe bars 26 being pivotally connected to the depending flange 2'! of the bar 28, which forms a part of the disc structure.

Spring members 2! are secured to the flange 21 and engage the bars II, normally urging the lower endsof the bars outwardly'and upwardly. As shown, the lower ends of the bars 26, are supplied with rollers 30 that flt within the open side of the channel bar I, with the result that when the bars a swing outwardly and upwardly, the win-- 50 dow ,I, supported by the channel bar C, will be elevated.

The control switch of the device is indicated by the reference character 3!, which control switch embodies contact members 32, 33 and 34, which contactmembersareincircuitwithasuitablesource of electricity supply, through the wires 3! and II. Movable switch blades 31 form a part of the control switch, and are in circuit with the motor ll, through the wires 38. Coiled springs indicated at 3! connect with the operating arm of the control switch, to normally hold the control switch in position. Thus it will be seen that due to this construction, when the control switch is moved to complete a circuit between contact members 32 and I3 and switch blades 31, the motor II is operated, which rotates the shaft l4,

Assuming that the window is in its open position, or the position shown by Figure 1 of the drawings, as the motor operates the shaft H, the collar I! will move upwardly over the'shaft ll, causing the lower ends of the bars 2 to swing outwardly and upwardly, elevating the window.

When the window has reached, the desired height, the switch is operated to break the circuit to the motor.

Should it be desired to lower the window, the

. switch is operated in the opposite direction, caus- Havingthus described the invention, what is claimed is:

1. The combination with a vertically sliding window, of a window operator comprising a bar on which the window is mounted, a threaded shaft, a motor, a motor shaft extending from the motor, a friction clutch connecting the motor shaft and threaded shaft, a bearing in which the upper end of the threaded shaft is mounted, means for adjusting the bearing whereby .the friction clutch is regulated, and means for transmitting movement of the threaded shaft to the bar, whereby the bar and window are moved vertically.

" 2. The combination with a vertically sliding window, of a window operator comprising a bar on which the window is mounted, a threaded shaft having a head at the upper end thereof, a vertically adjustable bearing having a socket in which the head is mounted, a motor having a motor shaft, formed with an enlarged end, a disk at the lower end of the threaded shaft, a clutch member between thedisk and enlargement, means for adjusting the bearing vertically regulating the action of the clutch member, means for operating the threaded shaft, and means for transmltting movement of the threaded shaftto the 25
